MACHINERY FOR WARPING YARN.

Specificatonof Letters Patent No. 25,501, dated September 20, 1859'.

To all whom fit may concern:

Be it known that we, RICHARD GARsED and CLAYTON DENN,of the cityandcounty of Philadelphia .and State! of Pennsylvania, have invented a newand useful Machine for Warping Yarn, and do declare the following to bea full and exact description of the same, reference being had to theannexed drawings, making a part of this specification, in which- Plate1, lrepresents several views of the machine and different parts thereof.vPlate 2, represents the arrangement for `the stopmotion. Plate 3,represents the looping arrangement. Plate a, represents a cross-sectionof the cylinder 20.

' Our improvement relates to machinery for drawing the yarn from thespools and forming it into a warp or chain preparatory to sizing andbeaming.

Figure 1, Plate 1, is a side view of the ma'- chine. Fig. 2, is a topview of the-same. Fig. 8, is a view of the arrangement for thestop-motion. Fig. a, is a view of the linking arrangement. Figs. 5 and6, are views of the warp after the leas have been taken. Fig. 7,-is aview of a cross-section of the bar A, detached and in an uprightposition. Fig. 8, is a view of the pin 57, detached. Fig. 9, is a viewof the marking and registering apparatus. Fig. 10, is a view of thepinion B, with a portion of the rack 18. Fig. 11, is a view of thespring. or the back of the perforated ratchet index C.

Our machine consists of a series of spools D, D, D, D, etc., arranged ina suitable stand, as shown in Fig. l, Plate l, containing the yarn.These may be arranged on a series of upright stands placed at one end ofthe machine, as shown at E, E, E, Fig. 2, Plate 1.

F, in Figs. 1, and 2, Plate 1, is a plate perforated with holes throughwhich the yarn passes as it comes to the rollers G, G, from the spoolsD, D, D, D. The object of this plate is to prevent the tangling of thethreads, by keeping them separated. These rollers G, G, are for thepurpose of holding the yarn at a certain height, and preventing thetwist of the yarn from running from one part to another.

H, in Figs. l, and shaft of the machine.

The next portion of the machine is kwhat 2, Plate 1, is the main Thearrangement of the stopmotion is shown in Fig..3, Plate l, and alsoenlarged in Plate 2.

The same letters of reference in the two representations refer to thesame parts.

In Plate 2, Fig. 12, isa front view of the drop-wires, all in theirproper places, as they exist while the machine is running. Fig. 13, is aview of the same, but showing one thread broken and the correspondingdrop-wire having fallen. Fig. 14, is a view off'a single drop-wiredetached. Fig. 15, isan end view of the stop-motion arrangement. Thisarrangement consists of a finely balanced platform l, moving upon itscenter 2, one end of this platform is immedi-y `on which it playsloosely. The lever 5 is lsupported at its center upon a pivot. 6, Fig.

2, Plate 1, is a sliding rod, acted upon by a spring, which keeps itconstantly pushed outward. Upon its outer extremity is a guide, throughwhich the pulley-band passes. This is so arranged that while the rod 6is kept pressed outward, the band will be over the outer pulley, whichis a loose pulley, and when the rod G is pulled inward, the band will bepulled upon the tight pulley, and thereby move the machinery. 7, Fig.15, Plate 2, is a lever fixed upon a pivot 8, and kept vibrating bymeans of the eccentric 9 at its upper end. The dropwires, of the formseen in Fig. 14, plate 2, arearranged in rows, as seen in Figs. 12, 13,and 15, Plate 2, in such a manner that the wires of one row will beslightly above the wires in the preceding row.

The machine is started by pulling the rod G back by means of the handleX, thus throwing the band over the tight pulley. The rod 6 is retainedin this position by the upper extremity of the rod 5 catching in a smallnotch in the rod 6.

The yarn being drawn from the spools D, D, D, D, etc. through the plateF, and then between the rollers G, isA passed through the drop-wires insuch a manner that each thread passes through all the wires of its stackwhich are anteriorto it, but supports but a single wire. Thisarrangement can be better understood by an observation of Fig.k15,.Plate 2, showing an end View of one stack of wires with the threadspassing through. Should any thread break, the drop-wire which itsupportsmust necessarily fall. Its weight upon the platform 1 causes theplatform to fall, which, by means of its lever 3, raises the lever 4.The lever 7, in vibrating must now necessarily strike against the end ofthe lever '4, thus pressing against the lower end of the lever 5, andthereby drawing the upper end from the notch in the rod 6. The springaround this rod now forces it outward and by the arrangement previouslydescribed throws the pulleyeband upon the loose pulley, and consequentlystops the machine. It should be remarked that the weight of the platform1 should exactly counterbalance the weight of the levers 3 and 4.

After the yarn has passed through the dropwires, it is passed over aroller m, shown in Figs. 2 and 3, Plate 1, and Fig. 15, Plate 2. Theserollers are for the same purpose as the rollers Gr, G.

The next portion of the machine is the cut marking and registeringapparatus. This is shown detached in Fig. 9, Plate 1 and also in Plate4. 16, in Fig. 2, Plate 1, and Plate 4 is a worm upon the axle 17,turning a small pinion connected with the cam L in Figs. 2 and 9, Platel and Plate 4. This cam revolves in the direction of the arrow. 18 is arack, 19 is a spring arranged in such a manner that it will have atendency to push the rack toward the cam L. B is a small pinion; on thesame shaft is a small cylinder 20. This cylinder contains coloringmatter. 21 is a brush projecting from one side of this cylinder. C is aratchet, having a series of teeth around part of its circumference. Aseries of small holes are placed around near its edge. A hammer, 22, isalso fastened permanently to it. 23 is a bell.

As the cam L is revolved by means of the worm and pinion previouslymentioned, it presses back the rack 18, which causes the pinion B, torevolve, the hollow cylinder 20 being held stationary by a spring catch.The projection on the cam having now passed the end of the rack, therack, by the action of the spring, is carried forward to its formerposition, causing also the revolution of the cylinder'. In therevolution of the cylinder the brush rubs against the warp, and depositsa portion of the coloring matter upon it. On the back of the perforatedratchet-wheel C, is a coiled spring, as shown in Fig. 11. On the cam Lis a slight pin. This pin, catching in the teeth of the ratchet-wheel,carries this wheel around one tooth for each revolution of the cam, andconsequently for each cut. The spring, by this means, is gradually woundup. The ratchet-wheel is prevented from being carried back by aspring-click a. In

one of the holes of the ratchet-wheel is placed a pin, and a second pinis placed in a second hole, with as many holes intervening between thetwo asthe number of cuts desired in one warp. A small arm, 30, attachedto the aXis of the ratchet-wheel, and hanging loosely on it is permittedto hang between the two pins. As the ratchet-wheel revolves, the pinbehind the arm drives the arm forward until its lower extremity pressesagainst and releases the spring-click, and by catching in a notch orother suitable contrivance upon the spring-click retains it out of theteeth of the ratchet-wheel C.

The spiral spring on the back of the ratchet-wheel C immediately causesthe wheel to be thrown around. During this backward motion of theratchet-wheel, the l second pin striking against the arm 30, forces itfrom the spring-click e, thereby permitting the spring-click to returnto its positioni-n the teeth of the ratchet-wheel.. The hammer, which ispermanently fastened to the ratchet-wheel consequently strikes againstthe bell, thus givingnotice that a warp has been completed. Theoperation is then repeated. Any number of cuts may be had to a warp bysimply placing the two pins a corresponding number of holes apart.

R, R, Fig. 2, Plate 1, are the heddles. A is a rod supported by pivotson the frame of the machine, having upon its two sides a series oflingers, placed in such a manner that no finger on one sideA will bedirectly opposite to any one on the other. The fingers may, however, beplaced only upon one side. S are the reeds. T, and T, Plate 1, are tworollers, driven by being connected by beveled wheels or other suitablecontrivance with the main or driving shaft of the machine. T, is aguiding roller.

When the bell rings, indicating that the desired number of cuts haspassed through the machine, the attendant turns the bar A, as shown atFig. 7, Plate 1, which depresses every other four threads, or as many asare passed together between the reeds S, when hev inserts a rod 41, asseen in the drawing, after which he turns the bar down in a contrarydirection, and inserts another rod 42; thus he has 4 threads above, and4 under, throughout the width of the warps.

y He then raises one heddle, and consequently every other thread, whenanother rod, 43, is inserted; the other heddle is raised next, andanother rod, 44, is passed between. The threads then assume the positionshown in Figs, 5 and 6, Plate 1. The rods are replaced by springs, whichare secured, and the whole run through the machine. It is then cutbetween the beamers and the weavers leas, and the ends tied. The machineis now ready for starting again. The warp, after it leaves the reeds,passes between the rollers T, T and over the roller T. From here itpasses to the linking apparatus.

The linking apparatus is supported above the rollers T, 'Land is drivenby a band from the pulley on the roller T, to a pulley attached to themain shaft of the linking apparatus, and is shown in Fig. 11, Plate 1,and the vario-us positions of its loopinghooks etc. in Plate 3. Itconsists of a pair of rollers, P, P, Plate 1, Fig. 1,'between which thewarp passes after it has been col lected by passing through a hole inthe cross-piece Q. It then passes down through a vibrating tube V. Thistube is caused to vibrate laterally by being loosely suspended upon apivot above it. To a point near the upper extremity of this vibratingtube, one end of a bolt WV is attached-the other end of this bolt passesthrough a hole in the framework, for the purpose of grinding it. Aspiral spring is attached in such a manner as to cause the bolt toproject slightly beyond the frame work, and consequently causing thevibrating tube to incline toward that side. 51, Figs. 1, and t, Plate 1,is a toothed wheel, gearing into a corresponding toothed wheel on themain shaft. Upon the inner surface of this wheel is a cam soconst-ructed that during a portion of the revolution of the wheel 51, itwill press against the end of the boltv 1V, and thus push it in(counteracting the edect of the spiral spring) and consequently forcingthe vibrating tube over to the other side. Immediately beneath thevibrating tube is a stationary hook, grooved upon its upper surface, andhaving a slit upon its outer end, extending about one-third of itslength. 52, Plate 3, shows a side view of the extremity of this hook;53, Fig. 7, Plate 3, is a lever moving upon a pivot at 54;, and itslower end sliding in the groove of the stationary hook 52. To facilitateit in its movements, the lower extremity, which slides in the groove ismade a segment of a circle. The lever 53 is moved backward and forwardby being connected by a short crank with a wheel on the driving shaft. Amovable hook, 55, of a peculiar shape, as seen in Plate 3, is attachedby a pivot at the point 56, Fig. 7 to the leve-r The tail of thismovable hook is made slightly curved, and is acted upon by a stationarypin, 57, in the frame, in such a manner that the point of the hook 55will be alternately raised and depressed in its backward and forwardmotion. This portion of the machinery is designed for the formation ofthe loops.

Plate 3, represents the formation of the loop in its various stages. Theyarn, passing through the vibrating tube, is laid across the stationaryhook 52, as seen in Fig. 1, Plate 3, by the tube vibrating across it.The movable hook 55 then passes forward and falls in the slit in thestationary hook 52,

with its upper prong beyond hook 52; and the lower prong consequentlyrests upon the yarn. The movable hook 55 then being drawn back, carriesthe yarnback with it,

which being pressed between the lower end of the upper prong 60, and aprojection on the stationary hook 52, falls into the space between thetwo prongs. The tube V then vibrates to the opposite side, and lays theyarn again across the stationary hook, as shown in Fig. 2, Plate 3. Themovable hook 55 then passes forward, being raised at the same time bythe action of the stationary pin 57, and carries the yarn resting on itslower prong, which it previously drew back with it, forward and over theyarn just laid, by the vibrating tube upon the stationary hook, as seenin Fig. 3, Plate 3. The movable hook passes still farther out, as seenin Figs. l and 5, Plate 3, unt-il the prongs 60, 61, have completelypassed the points of the stationary hooks. Then by the action 0f thegravity, or of any suitable contrivance, the point of this movable hookis lowered, as shown in Fig. G, Plate 3. The movable hook is then drawnback through the slit of the y stationary hook, and thus forms a link.In

the backward movement of the movable hook, it carries back with it theyarn lying across the stationary hook, as shown in Fig. l, Plate 7. Theoperation is then the same as before. On each side of the prong 61 ofthe movable hook are slight grooves, in

which the points of the stationary .hook rest, as the movable hook ispassing between them. The object of these grooves is to cover the pointsof the stationary hook so that the yarn may not catch upon them.

The pin 57 is shown detached in Fig. 8, Plate 1. lt is made so as toslide in and out of a slight tube. A spring keeps it con stantly pressedoutward. The movable hook 55, in drawing backward by means of aninclined plane upon the side of its tail, presses the pin back out ofits way. The object of this sliding pin is to raise the 1nov able hookwhile going outward only.

It should be stated that the frame-work of the machine is sufficientlyhigh to enable the operator to pass beneath to examine the working of,and to adjust, the various parts.

Having thus described our improvement, what we claim as our inventionand desire to secure by Letters Patent is,

1. The form of the drop-wires, as in Fig. 14e, arranged in the mannerand for the purpose specified.
